Long Working Hours
Yoga : The issue is not so much working hours as the package deal; deadlines, competitiveness, etc. For every hour, take two minutes off to stretch, go for a small walk.
Cardio : Long work hours (upto 10 hours) are fine as long as you enjoy your work; 14-15 hours is overwork. If you dont enjoy your work, change your job before a heart attack.
Endo : Can be counterproductive because typically such jobs encourage sedentarism with high mental stress, which increases metabolic stress. For optimum heart health, two good four-hour sessions is the maximum allowed, anything more is risky for heart health.
Psych : its a package deal. improve your time management skills, delegate, intersperse work with recreation or fitness activities, have a support system at the workplace.
